Hand Crushable Cans Printer Friendly Version
We should add several wrinkles or ridges to our cans so that we can crush them by our own hands with no chance of them being crushed incorrectly and we get perfectly flat, crushed cans every time.
This saves the common can recycler time and gets rid of the frustration of having to crush them with your feet. If we run ridged dents around the can from top to bottom we can crush them by hand easily, completely flat and without effort.

Using wasted heat Printer Friendly Version
Anything that has a radiator is blowing off heat and wasting energy doing so. So why not use it to heat up NaOH which will remove the oxygen from it. This leaves you with NaH which when allowed to react with water creates hydrogen. Then you can use the leftover NaOH to do the same path again.
The idea of using NaOH to store hydrogen has been realised. They are called powerballs (http://www.powerball.net) but no concept of using the technology to capture all the energy we throw away through radiators on cars and such has not been used.
Just as a side note that people would probably wanna know about is the implementation of hydrogen onto diesel fueled vehicles as a combustion agent.
Reward: let me know you've done it.
